I have a prob in a tester's AWG (arbitrary waveform generator), the dc offset of the diff output are not good so I put coupling cap on the output of the AWG (to block the dc and pass only the AC signal) and put a resistor connected to an accurate DC source. With this the dc are now accurate but I think the AC signal affects by this RC ckt.
Do you have any suggestion how can I mix the AC and DC? I need 80Khz, 100mVpp with 1V dc.
